Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940402, here are decompositions:

3 + 940399 = 940402
41 + 940361 = 940402
53 + 940349 = 940402
83 + 940319 = 940402
101 + 940301 = 940402
131 + 940271 = 940402
173 + 940229 = 940402
179 + 940223 = 940402

Showing the first eight; more decompositions exist.
